Liquid silicone molding is a relatively common injection molding process for silicone product manufacturers. silicone compression molding At present, many solid silicone products that cannot be encapsulated use liquid molding process. Do you know its overmolding process and skills?
The conventional processing technology is mainly for the silicone manufacturer to put the main plastic or metal material in the mold to infuse the liquid raw material to seal the overall high temperature molding. The main problem of the product is that there must be positioning holes in the hard glue position or the upper and lower molds can completely seal the product. Positioning, liquid silicone injection molding can also be processed through the secondary molding process. The silicone and plastic are divided into two parts. First, the plastic is poured into the mold cavity and molded into the mold. After molding, there is no need to pick up the goods or remove the cape to form the injection silicone material.
The advantages of liquid silicone encapsulation products are mainly that the product bonding details are more beautiful and the product fit is more perfect. Therefore, although the efficiency of many liquid silicone encapsulation products is not high, the quality of the products produced is very good.
The main difference between it and the solid-state encapsulation process is the degree of encapsulation effect of the product. After the liquid encapsulation is completed, there will be basically no defects, cross-coloring and dislocation. There is still a certain impact in the case of product dislocation and offset, so the encapsulation functions of the two are formed at the same time, but the effects are indeed two.
